For now I've been using the NYT wirecutter folks. They do a good job posting their methodology and you can usually dig much further for what problems they found.
Whenever I visit them I get the opposite of Gell-Mann amnesia syndrome and remember how terrible their recommendations are on products I am familiar with.
I had to scroll through a whole lot to get to the part that mentions wirecutter - the only one they really mentioned was webcams, with anecdotes about how that particular webcam they recommend isn't very good. Not much talk about why the methodology is wrong.
However I do find the webcam recommendation article wirecutter did to be of worse quality than the others they had. Its a very room dependent item. Its certainly easy to look at that review having played with other webcams and say hey I think their methodology sucks.
But I recently bought a new toaster oven - I had already had a kitchenaid one that got fine reviews on most sites, but I found it to be really inconsistant. The wirecutter site had photos of the uneven toasting of the same model I had, in the exact same way that mine was. They also showed photos of their recommended toasters. I picked up their recommended one. It toasts exactly as they recommended. So its not a total loss.
